Answer:

-19

Step-by-step explanation:

x= -5       y = -2

-x^2 - 4xy + y^2

- -5^2 -4(-5 x -2) -2^2                      Plug in

+ 5^2 -4(-5 x -2) -2^2                      Change the signs for - -5

  5^2 - 2^2 - 4(10)                           Place Liked Terms together

  25 - 4 - 40                                    Subtract

Answer:

triangle pjl is congruent to it's by side side side theorem

Answer:

([tex]\frac{2}{3}[/tex], 2 )

Step-by-step explanation:

Given the 2 equations

3x + [tex]\frac{1}{2}[/tex] y = 3 → (1)

6x - y = 2 → (2)

Multiplying (1) by - 2 and adding to (2) eliminates the term in x, that is

- 6x - y = - 6 → (2)

Add (2) and (3) term by term to eliminate x

- 2y = - 4 ( divide both sides by - 2 )

y = 2

Substitute y = 2 into either of the 2 equations and solve for x

Substituting into (2)

6x - 2 = 2 ( add 2 to both sides )

6x = 4 ( divide both sides by 6 )

x = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]

Solution is ( [tex]\frac{2}{3}[/tex], 2 )

Answer:

8x²-10x

Step-by-step explanation:

In Solving This Equation You Will Need To Follow This;

Original Equation:

2x(4x-5) {You will multiply 2x by the ones in the bracket which is the 4x and -5)

So 2x Multiplied by 4x is doing to give you 8x² we have 8x² because x multiplied by x becomes 2 that's why we have x² so 2x Multiplied by 4x is; 8x²

And 2x Multiplied by -5 is -10x because positive multiplied by negative is negative and when the number is with a variable and you want to multiply it by a natural number it is possible but you can't add a number with a variable to a natural number

So the final answer is; 8x²-10x

Answer:

x=-35/6

Step-by-step explanation:

2 + 3( 4x + 5) = -53

subtract 2 from both sides= 3(4x+5)=-55

divide both sides by 3 = 4x+5=-55/3

subtract both sides by 5 = 4x=-70/3

divide both sides by 4 = x=-35/6

x=-35/6 is your final answer

Answer:

Hope this helps :)

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Exact Form:

x=−35/6

Decimal Form:

x=−5.8¯3 (Repeating)

Mixed Number Form:

x=−5 5/6

Answer:   37.2 pounds per liter

Step-by-step explanation:

The density of the material of 4 kg/cup on converting it into pounds per litre will be 37.2 lbs/lt.

Given that, the density of a certain material is such that it weighs 4 kilograms per cup of volume.

Defining a derived unit is the process of deriving a measurement unit from one or more of the seven base units of the international system of units (SI). There are two types of derived units: dimensionless and the product of base units.

Here it is given that, the density d of a certain material is 4 kilograms per cup of volume and it is finding the density of material in pounds per litre.

Now it is known that,

1 kg equals 2.2 pounds

Now, 1 cup of volume equals 0.237 lt.

Converting the density d of material in pounds per litre and rounding it to the nearest tenth:

d=4 kg/cup

=4×2.2/0.237

=37.13≈37.1 pounds/lt

Therefore, the density of the material of 4 kg/cup on converting it into pounds per litre will be 37.2 lbs/lt.
